Very interesting posts guys. I love this site as you learn something new every day
moonraker am I reading your post right? am I right in thinking that by leaving the meadow to its own devices I am helping the pignut population?
cheers

If you just leave a meadow to it's own devices eventually it will ultimately revert to a natural climax vegetation which throughout Britain is deciduous woodland
.
Basically through traditional methods of farming either through hay making or grazing, meadows and other species rich grasslands provide a specific habitat for plants such as pignuts. Therefore mans intervention on the land actually provides greater biodiversity.
This was true until modern farming practice introduced more intensive methods of cultivation, using artificial fertilisers which encourage certain grass species which grow quickly to smother out other less vigourous plants; use of selective herbicides which kill 'weeds' but do not kill the grass, thus improving productivity; killing everything with non-selective herbicides and replanting with perennial ryegrass species, often genetically bred now to again improve productivity of the field but offer mush less habitat to other plants, insects etc; small fields disappear as bigger modern farming machinery such as tractors means hedges get removed to make larger and larger fields; drainage of water meadows; changing away from hay making to silage and alternative crops, etc etc. All this means that this habitat has been in steep decline, especially since the last war.
It means that it is great if you wish to help retain such meadow or restore improved grassland back to this type of habitat!
Broadly it means not so much zero intervention, rather, brining animals onto the filed to graze or cutting the grass for hay, removing cuttings to keep nutrient levels lower (if you cut grass you simply add their nutritional value back to the land) which encourages species diversity, not spraying with chemicals etc. In some situations if the grassland has been really improved so there is little natural diversity except planted ryegrass, then more drastic action might be required like removing it and restarting over with carefully selected grass/ wildflower mixtures.
Really the best first step is to contact your local Wildlife organisation, perhaps viayour local authority who should have a conservation officer. They will often be very happy to offer advice or point you in the right direction. There is free literature available and also grants too (depends on scale etc). One note, sourcing seed with local provenience (ie comes from a source locally rather than from Poland etc!) is important.
No two fields are the same
And local expert advise will guide you as to the most appropriate management plan to produce a wonderful natural resource, and give you a good foraging ground for bushcrafting too
There is an interesting web site for Oxfordshire which will give a flavour of what it's about
